My experience has been the same as eric's.

Thank you, Eric and daisychain01. Your comments and experience have made me feel better. This morning, the granite looks a little lighter, I just hope it fades in the next few days. Thanks again.

Lacquer thinner will be better to remove the soap stain. Soak a paper towel with lacquer thinner, apply it over the darkened area, cover with plastic and tape it air tight to counter. It could take several attempts to completely remove the soap stain. Do not panic if area gets larger as you go. It just means the poultice is breaking down the soap and it will disappear. Most of the time the soap will dissipate with time if you do nothing. Once the stain is gone apply a good sealer per sealer instructions.

Corie Hall, I realize this is a very old thread but I am having the same exact issue with a marble counter. It is drying but I can still see a difference as the place where water wicked past stain is still slightly darker. Did your problem resolve with more time and drying?

Margo: Take a Bernz-O-Matic to your spot please.

Thanks Joseph. I actually put a fan on and the darkened area went away. So glad it was just water that had absorbed and not a stain.

I’m having a similar problem. I applied baking soda and water poultice to a light granite for 48 hours and am left with a large dark spot after cleaning everything. It’s been left for about a week to dry and only minimally improved. Took the dryer to it, now hot granite with a dark spot. Was hoping to get this taken care of before I seal the granite. Any assistance is more than appreciated.

Hi, I found the hair dryer didn't help but the fan worked. it took several days to dry out but it was perfect when it was finally dry. This has now happened twice when I left a wet towel on the counter overnight .Looks like I will need to reseal.Try a fan and give it a few days- my advice.

Fan is on. Fingers crossed. Will let you know how it goes. Thank you!

As I mentioned it took several days to completely dry-maybe 4 or 5.

tarullim Has your stone dried out?

Slowly getting better. I was out of town for a few days. Will check it tomorrow and see if it is back to normal. Thanks for checking in, it seems to be improving thanks to your advice.

It’s getting closer but still not back to normal. I’ve left the fan going. Any other thoughts?

It's a good sign that it is improving-give it a few more days with the fan. I did the same thing as you-made a poultice with baking soda and water,left it for two days and when I removed the plastic wrap, the water wicked past the stain and created a larger dark area. I called a local marble restoration place in NYC and they suggested the fan. Hope all goes well with yours.

" Any other thoughts?"

Have you tried the Bernz-O_Matic?

Have not yet but I think that’s the next step. Will let you know how it goes.

It seems to have improved on its own. I think it’s good for now. Going to seal it before anything else happens. Thanks!

The same thing happened to me on my white macaubus quartzite countertop. It has lightened a bit in 5 days. I just put a fan on it. How long do you think it would take to clear?
Thanks!

It took well over a week but in the end it was back to perfect. Just keep a fan on it and that should work.

Thanks Margo. It is frustrating to say the least. It isn’t mentioned in articles on poultice so it seems that it’s unusual. My stone is sealed, although it is honed and more porous.
I spoke to a stone guy who said it would dry on its own but the fan is a great idea.
I will keep you updated.

The advice you received is what I had been told by a marble restoration company.They told me to put a fan on it and that worked. I have honed Carrara marble
